Are you referring to the cigarette lighter/12V outlet function? Make sure you're testing it with the keys in the "on" position, or the engine running. I've only had my G6 for 2 days, (wife's new ride) and haven't gotten around to plugging anything into the 12v outlet yet to determine if it is always powered, or only with the key turned on. Regardless, the fuse panel, I believe is on the passenger side of the car. If you were sitting in the passenger seat, it would be the panel near your left foot - at the base of the center console.
